Benefits

Maximizes conversion of starch substrates to glucose/ maltose

Minimises residual carbohydrates

Low treatment costs and dosages

Dosage

In manufacture of glucose: The recommended dosage is 0.2-0.3L per ton of dry starch. Pullulanse and glucoamylase together can be used in saccharification step. The usage of pullulanse can improve the yield of glucose by reducing the content of amylopectin, and can reduce the usage of glucoamylase.

In manufacture of maltose: The recommended dosage is 1-2L per ton of dry starch. Pullulanase and Fungal Alpha-Amylase together can be used in saccharification step. The usage of Pullulanse can improve the yield of maltose, and can produce maltose syrup with content of 70% maltose.

Recommended Storage

Safety and Handling Precautions

Enzyme preparations are proteins, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
